Best Sound Meter (SPL - sound pressure level) is an app which can measure the actual sound level meter with decibels (dB). Sound meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (spl meter).

It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.

You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.

Remember that it's only a device for fun and please use it as an auxiliary tool.

Levels of Noise In decibels (dB) according to American Academy of audiology:

140 dB - gun shots, fireworks

130 dB - jackhammers, ambulance

120 dB - jet planes taking off

110 dB - concerts, car horns

100 dB - snowmobiles

90 dB - power tools

80 dB - Alarm clocks

70 dB - traffic, vacuums

60 dB - normal conversation

50 dB - moderate rainfall

40 dB - quiet library
